What is the page error?
page failure is an operation that occurs on a computer with virtual memory, a technique that allows parts of the hard disk to expand the physical memory of the computer. Most page errors are when the program attempts to access the information that has been placed in the virtual memory file on the hard disk. This is a normal virtual memory function and the computer responds by loading the relevant information into the physical memory. A more serious type of page error associated with computer accidents and errors may occur when the program is looking for information in a memory location that does not exist or is protected. This can cause defective hardware or poorly written software. Most systems also support the concept known as virtual memory, on which the site can be moved from a computer with a physical random access memory (RAM) and to the virtual memorus Y stored on the computer's hard disk and back to RAM as needed. Details of this complex memory management scheme are hidden from software; The application has no way, JAK to see if the page is loaded at the RAM or is in virtual memory. The page failure occurs when the program is trying to read or manipulate a part of memory that is not loaded into RAM or is located at an unexpected address.
Despite the sinister name, the page error is generally normal and expected, and most of the time the user will never notice that the failure has occurred. It is a type of operation known as "trap", which means that instructions from a program that caused a failure are temporarily captured or captured, while the computer examines the address of the memory. If the address is valid, but is not currently loaded in the RAM of the computer, the information is transmitted from the Ual virtuscap on the hard disk to the physical memory and the program restores normal operation. This is known as "replacement" or "paging" and is common for almost any personal computer, regardless of the operating system or the amount of installed RAM. However, too little RAM causes the computer to constantly mix the memory pages between the hard disk and the physical memory, which worsens performance.
The second possible result of the page failure occurs when it is found that the required memory address is invalid or protected. This type of error, also known as the fault of segmentation, may be due to memory module failure, defective hard drives or incorrect software behavior. A special signal is sent to the program that triggered an error, which usually causes suddenly stop the program. Depending on the operating system, the most serious page errors may cause computer operating system failure, so users with a cryptic blue death screen (BSOD) or a panic of the core of the mess.
